Z22YH Vectra c p0302

Hi Everyone.
My 2004 Vectra c has started misfiring at high revs. Fault code p0302. Misfire no2.
No other codes. Same code comes back when reved hard under load again
Check all the plugs and they're sooty black. Wondering if it the plugs, coil pack or something else?
Hope someone can help.
Cheers in advance.

I would try a coilpack first, then swap injector 2 with number 1 and see if the code changes

Thanks vocky,
Changed the coil pack and plug, it improved and got rid of the misfire,but still wasn't running right. It had a seimens pump on it, so I got a nearly new continue one of eBay. Fitted it and it runs like a new car.
Thanks again
